The Undertaker returned on the February 21st, 2011, edition of RAW. his return was immediately interrupted by a returning Triple H who had also been absent for several months. The two men stared each other down and both peered at the WrestleMania marquee. As The Undertaker looked at Triple H, he performed his taunt, but in return, Triple H performed his crotch chop taunt. On the March 7, 2011 episode of Raw, the Undertaker stated that his match with Triple H at WrestleMania XXVII will be a No Holds Barred match. He also declared that Triple H will not be able to end his undefeated streak at WrestleMania XXVII, and that the Game will ' Rest In Peace '.
That hasn't been decided yet. Undertaker and Triple H haven't battled yet but I'm guessing that Undertaker won because he has a 18-0 Streak
undertaker and yokozuna sorry but yokozuna hasn't been in a Buried Alive Match but has had two casket matches with The Undertaker The first Buried Alive Match was at IYH: Buried Alive on October 20, 1996, between Undertaker & Mankind, Which Mankind eventually won with the help of Some other Superstars The second Buried Alive Match was at Rock Bottom on December 13, 1998 was between the Undertaker and Stone Cold , Stone had help from Kane to win The third Buried Alive Match was on the September 9, 1999 edition of Smackdown!

Because goldberg is to scared of the undertaker
according to triple h hes been out for 9 months
Undertaker has never been DEFEATED by submission. He has tapped, but never defeated through Submission. Another answer: Undertaker has never tapped out.
Apparently the undertaker has been spotted but there is also reports that triple h could promote the chaperone.
